No. 206,427 Claims priority, application France, July 7, 1961,867,249, Patent 1,301,419 3 Claims. (Cl. 128-287) This invention hasreference to diapers such as those used particularly by babies, infantsor young children and relates more particularly to such diapersincluding an absorbent strip of cellulose wadding or like material cutto size for incorporation with the diaper from a continuous mother bandor web of such material.

An object of the invention is to provide such a diaper of improvedstructure comprising an absorbent strip of novel and more adequate shapeadapted to be cut from a continuous mother band or web under betterconditions than in the prior art without producing waste materialAnother object of the invention is to provide a new or improvedabsorbent strip for diapers by cutting the same from a continuous motherband or web devoid of prior holes, recesses or slits.

A further object of the invention is to provide a new or improvedcontinuous mother band or web from which a number of strips or rows ofstrips for incorporation with diapers may be readily obtained.

A still further object of the invention is to provide an absorbent stripfor a diaper obtained by cutting it from a continuous mother band or webof cellulose wadding or like material, said strip having, viewed in planand widthwise, a shape made up of a part having rectilinear edges, awidened part and a narrowed part, advantageously of curvilinear outlinehaving an extension terminating in a rectilinear end flap.

Yet another object of the invention considered in a suitable embodimentis to provide an absorbent strip comprising a layer of cellulose waddingor like material sandwiched between two plies of unwoven material andprovided on its outer face with .a covering of imperivous material andon its inner face with a lining of liquidabsorbing substance.

The outer covering of impervious material of this absorbent strip for adiaper may be constituted by liquidproofed cellulose wadding oralternatively by a sheet of highly supple plastic such as vinylchloride. The inner lining may be made of liquid-absorbing cotton woolor alternatively of an absorbent cellulose textile material.

Owing to its particular shape, a number of absorbent strips for a diaperaccording to the invention may be cut in staggered Orhead to tailfashion from a continuous mother band or web, whereby .an importantsaving in material may be achieved.

The invention permits a continuous mother bandor web to be provided forcutting diaper strips from it, said band or web being, contrary to theprior art, devoid of preformed holes recesses.

In a convenient embodiment of the invention, one or several rows ofparallel diaper strips may be cut from a continuous mother band or webof suitably broad size. This band or web may have creases or lines ofminor resistance along which the diaper strips may be readily cut off.Slots adapted to be subsequently used as button holes may be providedadjacent each end of each strip.

With these and such other objects in view as will incidentally appearhereafter, the invention comprises the "ice novel construction andcombination of parts that will be now described with reference to theaccompanying dia grammatic drawing exemplifying the same and forming apart of the present disclosure.

In the drawing:

FIGURE 1 is a plan view of an embodiment of the strip for a diaper.

FIGURE 2 is a considerably enlarged sectional view of an embodiment ofthe mother band or web showing its laminated structure.

Reference being had to FIG. 1, it will be seen that the improvedabsorbent strip utilisable in a babys diaper and cut from a continuousmother band or web 7 comprises widthwise of said band or web fivesequential integrally connected parts, namely a part 1 havingrectilinear edges, a widened or bulging part 2, a narrowed orconstricted part 3 having inwardly curved edges, and an end part 4terminating in a flap 5 bordered by rectilinear edges.

The part 3 has in its narrowest portion a width smaller than that of theparts 1, 5 having rectilinear edges. Said part 3 may have a thickerportion (not shown) which can overlap the contiguous zones.

The width of the end part or flap 5 can be larger than that of the otherend part 1. Advantageously the widened or bulging part 2 has a sizelarger than that of the part 4.

The side edges 6 of the strip maybe more easily separated from themother band or web by providing in the latter creases or weakening lineswhereby said strip may be readily torn off the mother band or web. Slots8 may be provided along and adjacent the edges of the mother band or webso as to form button holes in the absorbent strip when the latter isformed into a diaper for'babys wear.

In the showing of FIG. 2 is represented in section a laminated motherband or Web from which strips may be cut off.

The mother band or Web may be simply a band made 0 cellulose wadding.However in the showing of FIG. 2, the band comprises a layer or ply ofcellulose wadding a provided on its inner side i.e. that side, which isadapted to come into contact with the babys crotch,-with a lining madeof a liquid-absorbing unwoven substance b (e.g. cotton, wool or anabsorbent textile or cellulose substance) and is provided on itsopposite (outer) side with a covering 6 made of an unwovenliquid-proofed substance. The covering 0 may be also made of cellulosewadding just as the lining a provided that it has been renderedimpervious. Alternatively the covering c may be made of a highly suppleor pliant plastic such for example as vinyl chloride.

Minor details may be varied without departing from the scope of theappended claims.

What is claimed is:

1. Diaper means for use on an infant comprising an elongated sheet ofabsorbent material having a series of diapers partially cut transverselytherein so as to be readily removed therefrom, every other diaper insaid series when viewed in plan having a first section defining 'asubstantially rectangular configuration, a second section extending fromsaid first section and having outwardly curved sides, a third sectionextending from said second section and having inwardly curved sides, anda fourth section extending from said third section and defining asubstantially rectangular configuration; the width of the narrowestportion'of said third section being narrower than that of said first andfourth sections; the other diapers disposed between said every otherdiaper having the same configuration thereof but in the oppositedirection thereto to save material; each transverse line of partial cutforming one edge of'two diapers disposed one on either side of sai line.

2. Diaper means as claimed in claim 1, said sheet being laminated andcomprising an outer layer of liquid-proof 2,896,626 7/59 Voigtman128-287 material and an inner layer of absorbent material. 2,926,6663/60 Casper 128284 3.
